Member Function Documentation

◆ value()

template<int dim>

double Functions::SlitSingularityFunction< dim >::value	(	const Point< dim > &	p,
		const unsigned int	component = `0`
	)		const

virtual

Return the value of the function at the given point. Unless there is only one component (i.e. the function is scalar), you should state the component you want to have evaluated; it defaults to zero, i.e. the first component.

Reimplemented from Function< dim >.

Definition at line 1383 of file function_lib.cc.

◆ value_list()

template<int dim>

void Functions::SlitSingularityFunction< dim >::value_list	(	const std::vector< Point< dim > > &	points,
		std::vector< double > &	values,
		const unsigned int	component = `0`
	)		const

virtual

Set values to the point values of the specified component of the function at the points. It is assumed that values already has the right size, i.e. the same size as the points array.

By default, this function repeatedly calls value() for each point separately, to fill the output array.

Reimplemented from Function< dim >.

Definition at line 1399 of file function_lib.cc.

◆ vector_value_list()

template<int dim>

void Functions::SlitSingularityFunction< dim >::vector_value_list	(	const std::vector< Point< dim > > &	points,
		std::vector< Vector< double > > &	values
	)		const

virtual

Set values to the point values of the function at the points. It is assumed that values already has the right size, i.e. the same size as the points array, and that all elements be vectors with the same number of components as this function has.

By default, this function repeatedly calls vector_value() for each point separately, to fill the output array.

Reimplemented from Function< dim >.

Definition at line 1422 of file function_lib.cc.

◆ gradient()

template<int dim>

Tensor< 1, dim > Functions::SlitSingularityFunction< dim >::gradient	(	const Point< dim > &	p,
		const unsigned int	component = `0`
	)		const

virtual

Return the gradient of the specified component of the function at the given point.

Reimplemented from Function< dim >.

Definition at line 1471 of file function_lib.cc.

◆ laplacian()

template<int dim>

double Functions::SlitSingularityFunction< dim >::laplacian	(	const Point< dim > &	p,
		const unsigned int	component = `0`
	)		const

virtual

Compute the Laplacian of a given component at point p.

Reimplemented from Function< dim >.

Definition at line 1447 of file function_lib.cc.

◆ laplacian_list()

template<int dim>

void Functions::SlitSingularityFunction< dim >::laplacian_list	(	const std::vector< Point< dim > > &	points,
		std::vector< double > &	values,
		const unsigned int	component = `0`
	)		const

virtual

Compute the Laplacian of one component at a set of points.

Reimplemented from Function< dim >.
